The Protestant Truth Society (PTS) is a Protestant religious organisation based in London, United Kingdom.
It was founded by John Kensit in 1889, to protest against the influence of Roman Catholicism within the Church of England and the nation.
In 1898 it sent out the first band of "Wickliffe Preachers" to spread the message. To train them, it established the Kensit Memorial Bible College in Finchley in 1905; this opened in 1908.
The PTS may still be nominally active, based in Fleet Street, London.
